Jaw-strength training is where you put random items
in your mouth and chew them from boredom. But somehow
in the end, leaves your jaw hurting like you just ate out a
humongous pussy.
Joe : "Chris, why are you not eating my asshole out aggressively tonight?"
Chris : "Sorry Joe, I had a tough jaw-strength training session earlier"
Joe : "Oh well
let me suck your dick then."
Oh boy, I feel like I just ate a
humongous pussy out. Must have been the jaw-strength training.
